POST-DRIVING MACH-INE.'

SPECIFICATION forming part of Letters Patent No;l 601,196, dated March22, 1898.

Application iiled February 24, 1897. Serial No. 624,657. (No model.)

To all whom it may concern: y

Be it known that I, GEORGE B. MGOLELLAN DEIHL, residing atWashingtonville, in the county of Montour and State of Pennsylvania,

have invented a new and useful Post-Driving Machine, of which thefollowing isa specifilvide a portable machine which is simple andeffective in operation and especially adapted for use on uneven groundor upon an incline.

My invention consists of a suitable tower or framework upon which theoperating mechanism is mounted, and a suitable box or trough hinged tothetower in which the post is placed. The driving-weight, which' isintermittently raised or dropped by the operating mechanism, is alsoplaced in the trough, so that it will always be guided onto the post.

My invention also consists in providing a novel construction ofoperating wheel by means of which the weight is intermittently raised ordropped while the said wheel is continually revolved in one direction.

My invention also consists of certain other details of novelconstruction and arrangement that will be hereinafter fully described,and pointed out in the claims.

In order that my invention may be more fully understood, I will proceedto describe the same with reference to the accompanying drawings, inwhich- Figure 1 is a perspective view of my invention. Fig. 2 is avertical sectional view thereof. Fig. 3 is a top plan view. Fig. 4 is adetail view of the guide-box connection and the hoisting mechanism. Fig.5 is a vertical sectional view,showing myinvention in use upon anincline. Fig. 6 is a detail view of a portion of the pulley, showing thethrow-o.

In the said drawings, 1 represents the up-I rghts of the tower orframework, which are secured together in the position shown by the topcross-pieces 3 3a, and by the lower crosspieces 2 2a, and supported onthe cross pieces or braces 3 are the parallel supporting beams 4a.

5 represents the power-shaft, suitably journaled in the boxes 4, and itis provided at one end with the crank 6 and at its other end with thegear-wheel 7.

8 represents a ratchet on the shaft 5, and 9 a pawl, which is for thepurpose of holding the shaft when the drivingeweight 16 is raised to anyheight.

y10 represents a shaft suitably journaled in boxes 5a, and it has fixedto it the gear 12, which engages with the gear '7, and the groovedpulley 11, which has one flange preferably higher than the other, and aconvex face 11a, which permits the rope or chain to pass easily overthat side when thrown out of the groove by the cam or throw-off 21a.

16 represents the drivin g-weight and is suspended from the pulley bymeans of a rope or chain 16, which has a swivel connection both with theweight and pulley. The weight may be of any desired shape and may be asheavy asv desired, and it is preferablyalmost as large in circumferenceas the interior of the box or trough, so that it will be guided in itsdescent by the box or trough. It will be understood that the weight isintermittently raised and dropped, and this is accom-y plished by the.cam or throw-off 21, placed in the pulley-groove. It is formed by thebolt 23, which is bent at one end, as shown, so as to form the incline23, which guides or throws the cord out of the groove and allows theweight to drop upon the post. The other end of the bolt fits in anopening in lthe pulley and is provided with aneye 23h, through which thebolt 23c is passed for keeping the throw-off in position.

13 represents the guide box or trough open at both ends and provided atone end with the hooks 14, by which it is suspended from the top of thetower, and at its other end with the hinged door 21, through which theposts are inserted in the trough or box. The door is held in closedposition by means of a hook and pin. As above stated, the trough or boxis suspended from the top of the tower by means of the hooks 14, whichengage with the hooks 15, depending from the supports 4a, or with thehooks 26, carried by the supports 3. I prefer this manner of suspendingthe trough or box, as it permits it to be swung or tilted, as the casemay require, according to the nature of the ground on which the machineis standing. The two sets of hooks are proa vided so that the trough orbox can be tilted in directions at right angles to each other.

In order to steady the box or trough and also to provide for anadjustment in certain directions, I employ the board 18, having theopening 17, through which the trough or box passes, and the series ofopenings 1W. A pin 19 is adapted to be passed through any of theseopenings and into one of a similar se ries of openings provided in thecross-pieces 20. This arrangement is particularly advantageous when themachine is used on an incline (see Fig. or upon uneven ground.

24 represents a platform xed to the side of the tower upon which theoperator stands, and 25 represents a ladder by which the tower isreached.

In Fig. 5 I have shown the machine in use on an incline. This ispermitted by reason of the connection between the trough and supportswhich permit the trough to swing or be tilted. The advantage of theboard 1S and its means of adjustment are apparent when the machine isused on an incline or uneven ground, for it is always possible to getthe trough in a vertical position, and also, if desired, the troughcould be tilted, so that the post will be driven at an angle. The wholemachine is mounted upon runners or upon wheels or rollers, as preferred,so that it can be easily moved from place to place.

The operation of my machine is as follows: The machine is placed tostraddle the line of fence and the post inserted in the trough or box 13through the door 21, which is afterward secured by the hook and pin. Theweight is then raised by the mechanism shown,which is continuallyoperated, and as the cord or chain is wound upon the pulley the cam orthrow-off guides or throws the cord or chain off and allows the weightto fall upon the post. This operation is continued until the post isdriven to the desired depth, when the machine is moved to the nextposition for a post.

Changes in the form, proportion, and minor details of construction andarrangement may be made without departing from the spirit and scope ofmy invention. Therefore I do not wish t0 be understood as limitingmyself to the exact construction and arrangement as herein shown anddescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 1. In a post-drivin g machine, the combination of theframework, the driving-weight, a guide box or trough movably suspendedfrom said framework, suitable means in connection therewith forsteadying said box or trough, consisting of a suitable board providedwith an opening through which the trough or box passes, and a series ofopenings, a pin adapted to fit in said openings and similarly-formedopenings in the framework, and suitable mechanism for operating thedriving-weight, substantially as shown and described.

2. In a post-driving machine, the combination of' the framework ortower, a guide box or trough suspended from said tower, a driving-weight, suitable mechanism having a pulley connected by a cord orchain with said weight for raising it and a cam or throw-off for saidcord or chain carried by said pulley and formed from a bolt secured inthe pulley and having an inclined part which engages the cord,substantially as shown and described.

In a post-driving machine, the combination of the framework or tower,the drivingweight and mechanism in connection therewith for operatingit, a guide box or trough provided with hooks adapted to be movablysuspended from said framework or tower, two sets of hooks arranged atright angles to each other carried by said frame and adapted to beenga-ged by the hooks of the box or trough, and suitable means forholding said adjusting box or trough, substantially as shown anddescribed.

t. In a post or pile driving machine, a pulley wheel or drum having agroove, the walls of which are continuous, provided with a throw-offarranged in said groove, inclined inward from the top of the outer wall,substantially as described.

5. In a post or pile driving machine, a pulley provided with a groovewith continuous i walls, one of which is higher than the other,

and having an inclined throwoff in said groove reaching from the outeredge of one wall to the outer edge of the other wall, substanti-ally asdescribed.

6. In a post or pile driving machine, a pulley having a groove whosewalls are continuous, provided with a throw-off in said groove,consisting of a wire or rod secured in the body of the pulley,projecting radially therefrom into the groove, and having its outer endbent to cross the groove in an inclined position, substantially asdescribed.
